Every single flight I take with southwest is delayed by at least one hour. Unbelievable

When I made my reservation it would have been nice if kayak would have included my luggage. Unaware that I had to pay $45 each way. Should have asked at reservation time if luggage was being checked

Crew was a little surly. But plane left on time and arrived early. All one can ask for. New 737 Max was nice.

Flight was delayed about 50 minutes and completely full. they did the usual demand for people to check carry-ons. they called all groups to board very fast only to stand in the gangway after having boarding passes scanned. Why don't airlines board from the back to front - since they now have assigned seats? our stewardess got drink orders confused, so she just called out "cranberry". etc.,.. I wish they wouldn't serve pretzels snacks with a powdered coating, as it sticks to your hands and they don't have wet wipes. don't want to lick my fingers after hanging out in the terminal for over an hour.

Delayed over 3 hours, extremely rough landing on all four flights. Would not recommend

Boarding, crew and inflight entertainment was great. Could have better food options for a long flight. Paid money and got a seat with extra leg space but was asked to keep my carry on under the seat in front of me which defeats the purpose of buying a extra space seat.

On time departure and arrival. Had to be the oldest plane in the SWA fleet but it got me where I needed to be.

Flight was delayed out of BWI unexpectedly / without a reason given but otherwise ok.

I got a bit sick on the flight, and was so grateful when the male flight attendant explained to me they keep the back row open for cases like mine. He took such great care of me! I was incredibly grateful.

Boarded the plane in Portland and sat on the tarmac for four hours before being given clearance to take off. Apparently a "scratch" was detected on the preflight inspection. This delay resulted in me missing my connection in Baltimore. I therefore had to stay overnight and then catch an early flight this morning, which resulted in my missing a mandatory class. I would like a refund / voucher to cover the cost of the missed flight. And additional voucher for the time spent on the plane in Portland would also be appreciated.

Great overall experience and use of the Delta One lounge was amazing!

I used by Skymiles to upgrade to First so that I could comfortably work using my laptop. But WiFi was intermittent and unavailable for long periods. I feel like I wasted 70,000 miles :(

Great as one can be for a one connection 6 hour flight

Packed flight and not sure why dinner service would start at midnight while passengers we’re trying to sleep

The gate attendant was not clear w message on flight delays.

Chairs don’t recline and the ones that do recline, barely do recline. It was most uncomfortable flight i ever been on.

Easiest airport experience ever in my life at MSP with Delta check-in and flight attendant gave us a bottle of champagne in celebration of our 10-year wedding anniversary, so overall amazing!

Great. Seamless. Check in agent at kiosk international was amazing and extremely helpful.

Delta did an awful job w logistics at DTW. Missed connection. We were there an hour early. SUCKED

Delta planes have the WORST seat comfort of any plane in history. It's the opposite of ergonomic, in every sense. They also recline minimally, are covered in a vinyl and have no feet rests. Then the disembarking process is chaotic and time consuming (because of the way they load the plane and deal with luggage). Overall, somewhat frustrating but we arrived safely :)

Set on the plane for two hours before pushing off the gate due to the power source issue being fixed which was known before letting people board the plane. On top of that it was very hot as AC was not working properly. Terrible experience and limited communication provided by the crew on the status of the issue. They should let people deplane while issue is addressed instead of frying them and glued to the seats.

I am United’s newest fan. The planes are clean, the staff is so friendly and snacks are more than just old pretzel crumbles. The captain came and said hello! Truly amazing experience

1 person checking us as we boarded, left gate on time, 12.30 we are told we were held for 15 mins as other flights were waiting to take off, captain due to rain … they were having a longer gap between take offs , 3pm we took off , they went land route via New Orleans in to Florida landed at 5.45pm offered coffee and a biscuit

Service was slow Flight was very loud at back of plane

There was no internet on the flight. As an executive flying during prime business hours, having internet is critical for a smooth experience. This impacted productivity and time that will need to be spent later to do the work I could have done on flight.

Both my flight where delayed Had 25min to make it to my transfer flight

My experience on this United Airlines flight was highly uncomfortable, primarily due to two issues: Cabin Temperature: The temperature on the Boeing 737 MAX 8 was unacceptably high, feeling consistently around 80 degrees throughout the flight. This made sleeping impossible and significantly detracted from the experience. Seating Arrangement: Being stuck in a middle seat for a six-and-a-half-hour overnight flight compounded the discomfort. Moving forward, I will always purchase a seat assignment to avoid this situation.

I just got back from a trip with 3 flights each way. The flights were good and we were happy with out experience. There was one steward on our first flight that was harsh and grump with passengers. It did not leave a good impression. All of the other flight crews were great on the other five flights.

They changed my flight 5 hours before it took off and changed my connecting airport messing up my entire 1st day in Japan.

I had very little time to change planes originally in Denver after my flight from Omaha. I had an hour and a half layover in Denver originally and my flight leaving Omaha was delayed an hour because they had to change a tire, which I can understand. When I reached Denver my other flight was late, fortunately, but I still had only 10 minutes to run about a mile through the airport to get to my flight. Again, fortunately, I am a healthy 71-year-old and was able to accomplish this feat. However, the stress was more than necessary to bear.

Plane was very comfortable,ore legroom, help yourself snack are so weren't disturbed by staff passing up and down cabin, gluten free food availability and really efficient and friendly staff . Boarding and good to time. Highly recommend t

The boarding agent and checked bag agent were both rude. It only takes a second to be kind. However, the flight crew was amazing. I got a turkey sandwich and it wasn't bad---not great but not bad. The internet was my biggest problem. This was a work trip and I REALLY needed the internet to meet a deadline but it didn't work for 80% of the trip. Very disappointing.

I tried to check in beforehand from Ireland. The Jet Blue website sent me to the Aer Lingus website and vice versa. I tried to get a boarding pass at Dublin Airport as well, but they said they couldn't help me either. I had to wait until I arrived at the gate in Boston to secure a boarding pass...it was a bit nerve wracking.

Great flight. Best in years. Very clean craft. Easy boarding. Communicative pilot. Friendly flight attendants. Absolutely smooth take off, in flight and landing. Very comfortable seats. Smoothest flight I've experienced in years. THANK YOU JET BLUE!

I was asked to pony up an additional $239 (over the $735 paid originally) for a one way middle seat, which was very uncomfortable. Where did you expect me to sit?

What's not to like? Value?definitely. Every JetBlue member was extremely friendly on this flight. Very very nice new-ish aircraft,plenty of room. GOOD coffee. Entertainment,I didn't need it,but I think its available. What to do better? Well,there's nothing we can do about the other people, unbelievable how some folks are operating. Just don't allow people to lug all their stuff onto the aircraft. 1 bag. That's it. Be easier for you too. I personally would enjoy more options in schedule. One flight in and out a day is warranted given the local,I understand, but the times are inconvenient. Again, I completely understand why it is that way,It would however be great to have different options.

see my previous response about being kicked off the flight and having to fly the next day, ruining a planned vacation tour.

The flight departed more than 1 hour late. Leg room is bigger than most airlines

terrible. Because I felt very unwell during the flight. How do they leave a woman alone in the middle of 2 men? an obese man who was falling on top of me.

I booked this flight using JetBlue points and I was just so happy. The plane was so clean, I had every need met. Thank you!!

It was unfortunate that the plane had mechanical issues and delayed our flight, but I am glad we made it safely! On the first American flight from Charlotte to Phoenix, they changed the gate without getting a notification, and I had to make a mad dash!

The intuit carrier I have flown with that doesnt have WiFi available on board - at least not on the A380. Meal I wanted wasn't available and the meals I did get were all served cold to warm at best.

The flight was delayed several times as they didn't have pilots. Then we were boarded on the plane and again waited on the tarmac for over 30-40 minutes waiting for pilots to board. The in flight entertainment was confusing at best on how to use it. It took multiple attempts to get wifi to connect and by the time it worked the flight was almost over.

The flight was delayed and gate changed so that was not fun and the flight to Dallas from LAX was very delayed on Sunday. It was just not a great experience due to the delays both ways.

Both directions of our trip were befuddled by massive delays, one of which led to our connecting flight being grounded mid air due to storms that we’d have missed if we were on time. The other our originating flight was delayed repeatedly until it arrived at our connecting airport later than our final leg was even supposed to have arrived. American cannot seem to manage rebooking s for a family party… both directions we had to come up with a plan to get to Boston stay overnight only one night each direction was covered by the airline -and take a bus to or from our destination. Missed an entire leg of our trip, hotel cancellation fees, expensive stay in Boston and bus ticket expenses are unlikely to be comped and the meal vouchers are worthless.

My flight was 4 hours delayed on departure at 6a causing me to miss my connection at DCA. I had to scramble to find a seat home on a later flight and instead of an exit seat, I was in row 30 on a flight getting me home 5 hours later than planned. The AA team on the ground did a fine job. AA continues to run the airline like the passengers are cargo.

The plane was probably full boarding was easy. We were able to check our carry-on luggage for free. It was a return flight through Philly to LA. Never saw a stewardess do a demonstration of emergency Procedures. I think my flight was pretty full

A much better flight than our previous. The flight attendant took care of us and regularly checked in to see if we needed anything. Brought us drinks prior to the departure and then a couple more times. Totally makes the difference in how you travel when the crew is checking on their passengers. Great job on this leg of our trip.

Flight was delayed after boarding and no idea when it would take off. Crew in Portland did arrange for transport to Boston for a different set of flights to my destination.

Seats are so close together. Middle seats should be discounted.
